Exploring the Universal Plug and Play Architecture
In this article, I presented the basic concepts of UPnP, a very flexible standard that lets computers, peripherals, appliances, and electronic devices automatically connect and share services. By defining and publishing UPnP device and service descriptions through the BRisa UPnP framework, developers have an open source, but powerful, mechanism to simplify the implementation of devices and services.
In this article, I focused on the UPnP Audio and Video specification, but the BRisa UPnP framework also provides extensible resources to implement other kinds of UPnP services, such as tools for controlling home automation devices.
The BRisa UPnP Project is getting attention from many developers, but, like other open source tools, BRisa is a work in progress. We are currently developing BRisa plugins for some well-known online services, including Yahoo Music, Facebook, Orkut, and PicasaWeb. These plugins will let users centralize all their Internet-based multimedia content in one convenient and flexible UPnP service provided by the BRisa media server.
